Weibo (graph anomaly detection)

Weibo users connected by shared hashtag activity, with labeled suspicious accounts. An organic (non-injected) anomaly dataset used throughout the BOND benchmark line of work.

Nodes	8,405
Node features	400
Edges	407,963
Outliers	347 (4.1%)
Label type	proxy
Label source	suspicious-account labels via the BOND benchmark

Files. nodes.parquet (node_id, feat_*, label, split masks where available) and edges.parquet (src, dst, the edge list as shipped upstream; symmetrize for undirected use). Ships the upstream single split as train_mask_0, val_mask_0, test_mask_0.

A provenance note this card refuses to paper over: the upstream README table lists 868 outliers (10.3%) for Weibo, but the shipped weibo.pt file contains 347 (4.1%). The numbers on this card describe the actual file (sha256 of the source zip: c4a5fe4c...). If you compare against papers reporting the 10.3% variant, you are not using the same labels.

Load

import pandas as pd

nodes = pd.read_parquet("hf://datasets/JaySuryavanshi/graph-anomaly-weibo/nodes.parquet")
edges = pd.read_parquet("hf://datasets/JaySuryavanshi/graph-anomaly-weibo/edges.parquet")

As a graph, with graphspot (pip install graphspot):

import numpy as np, scipy.sparse as sp, graphspot
from graphspot.detectors import XGBGraph

n = len(nodes)
adj = sp.csr_matrix((np.ones(len(edges)), (edges.src, edges.dst)), shape=(n, n))
g = graphspot.Graph(adj=adj, x=nodes.filter(like="feat_").to_numpy(),
                    node_labels=nodes.label.to_numpy())

Provenance

Mirrored unmodified (beyond format conversion to parquet) from pygod-team/data (MIT). Conversion is scripted and deterministic; label counts above are computed from the files in this repository, not copied from upstream docs.
